Abstract:

A novel method for preparation of high-solubility polyaniline(PANI) by one-step emulsion polymerization was reported with poly(2-acrylamide-2-methyl-1 propane sulfonic acid)(PAMPS) as doping acid and emulsifier by utilizing its unique long chain, hydrophilicity, and strong acid group. The structure and properties of the final product were investigated by nuclear magnetic resonance spectroscopy(NMR), Fourier transform infrared spectroscopy(FTIR) and scanning electron microscopy(SEM). The results shows that in the optimal preparation conditions of the reaction time 5 h, the polymerization temperature 5 ℃, the m(AN)∶m(AMPS)∶m(APS)=1∶2∶1.5, the mass fraction of AMPS and APS 20% and 30%, respectively, the yield of PANI is 86%, the electrical conductivity reaches 5.9 S/cm and the solubilities in organic solvent of DMF and water are 38% and over 21%, respectively.
